I have install a xonar essence stx ii 7.1 on my ubuntu 16.04 htpc. I was using the analog line in and the spdif (rca) output. Initally both worked. I did a standard ubuntu upgrade and neither worked. Reverting the kernel did not help. My system is dual boot with win 10. The sound card works on win 10. I tested the card (both when it worked and when it didn't) by playing music with kodi. I explicitly selected the stx spdif output device with the kodi system menu. I am looking for any suggestions to try. My ubuntu system configuration is -
